Lubrication Myth: Add Grease to a Noisy Bearing

This video explains why adding grease to a bearing that’s making noise may only provide temporary relief. Instead, a noisy bearing should be closely monitored and replaced as quickly as possible. When a bearing is making noise, internal damage has likely occurred. If the bearing continues to run without being replaced, more internal damage may occur with the potential for failure. Find out what you should check if the noise isn’t actually the bearing, as well as the possible causes of spalling, false brinelling, frosting and thrust load.
